Is there a way to prevent my wife from having any visitation with our four children?

You may want to seriously considering retaining a custody evaluator to perform a custody evaluation.  In contested custody disputes when parents do not agree on custody and a parenting time schedule, it is often necessary for one or both of the parties to retain a custody evaluator.  The evaluator is a professional who, after interviews, assessments, and more, recommends a custody and parenting time arrangement.  If, following the custody evaluation, the parents still do not agree on the evaluator's recommendation or on a different parenting time arrangement, it will be necessary to have a trial after which the judge will make the determination.
